Pickett Bridge Repair & Rehabilitation*

Pickett Bridge Repair & Rehabilitation
City of Bellingham

TranTech engineers, Kash Nikzad and Jim King were the Project Manager and Senior Structural Engineer on this project. PS&E construction documents directed to the repair and rehabilitation of Pickett Bridge were prepared in order to upgrade the structure to an HS25 live loading. This concrete arch structure built in 1927 is considered to be a very distinctive landmark along the Whatcom Creek watershed and trail system. The repairs included removal of the fill over the luten arch and installing a reinforced rigid concrete frame slab hidden over the arch and inside the faces of the existing side walls. Arch interior surfaces are sealed and a new interior drainage system is installed. The Public Works staff was assisted with presentations and briefings to the City Arts Commission.

Though not on the Register of Historic Bridges, the structure does possess several unique architectural features including the concrete handrailing. In the course of design, repair provisions designed to maintain the bridge’s visual appearance were developed. The project was funded through the Federal Bridge Program. The City was also assisted in preparation of the construction permits and bid documents.
